Best Deals : CarGurus

CarGurus

CarGurus

Why We Chose It

CarGurus lists dealer’s inventory across the country including new and used cars with an abundant number of affordable cars. 

Pros & Cons
Pros
  • Deal ratings for each car

  • Lets you compare vehicles on the market

  • New and used cars available

Cons

Unlike most online car buying sites, CarGurus lists both new and used cars. CarGurus doesn’t own the inventory it lists and doesn’t have dealership locations. Instead, dealers pay to list their cars on the site. Its standout feature is its deal ratings which let you know if the vehicle you’re interested in is rated as a great or a good deal or not a good deal to help keep you from overpaying for a car. 

CarGurus lets you get pre-qualified in minutes without impacting your credit score. If you’re approved, you will get personalized monthly payment information on the cars you’re interested in. You can also get financing through some individual dealerships. Return policies are also up to the dealer or individual selling the car, as are transportation costs, dealer fees, and test drives.

AutoTempest lets you sell your car, search for cars, or search car reviews. Its most impressive feature, however, is its car comparison tool which lets you compare the prices of cars across the country so you know that you’re getting the best price for the make and model you want.

AutoTempest’s search options allow you to filter cars based on mileage, location, and even specific sites. If you’re unsure where to start, it also has popular searches to get you started. AutoTempest also offers guides for first-time buyers and tools for comparing insurance and shipping quotes.

Tred

Tred

Why We Chose It

Tred offers peer-to-peer sales and handles all of the paperwork without needing a dealer or going to the DMV. 

Pros & Cons
Pros
  • Talk directly to the seller on the app

  • Offers financing

Cons
  • No return policy

  • Not as well known as other sites

Overview

Tred is a peer-to-peer marketplace for car sales. You can buy a car on the site, sell your car, or get financing through the company. It verifies that the seller is the legal owner of the car, checks to see if there are any liens on the car, and verifies the buyer’s identity and that the funds have been transferred. Tred does all the necessary paperwork so no visit to the DMV is needed. 

The company also works with major banks and offers car financing as well as insurance. Unlike many other sites, Tred lets you chat with the seller to find out more about the car before you buy. Tred users are located throughout the U.S. and shipping fees apply if you find a vehicle that isn’t in your area.

Tred doesn’t offer a return policy, so once you buy a car you’re stuck with it unless you can convince the seller to take it back. Although Tred lacks some of the more sophisticated tools and features that other sites have, it does offer helpful car buying and selling tips and a What’s My Car Worth calculator.

You can get pre-approved on the site, and you can also sell your car to them without being obligated to buy a car from them. 

Some of CarMax’s helpful tools include tips for first-time buyers, a car payment calculator, and optional service repairs and warranties. The company has 224 locations throughout the U.S. and offers free home delivery from most of its locations within a 60-mile radius.

Frequently Asked Questions

How Do Online Car Buying Sites Work? 

Online car buying sites come in all different shapes and sizes with different processes. However, the majority of them advertise cars from different dealerships on their site and allow you to search for specific cars, compare models, and look at ownership history, photos, and videos. Some even offer home delivery and financing applications directly from the site. 

Car buying sites are designed to make the car shopping process easier and less time-consuming. You can search near your home or across the country for a car all from your smartphone or computer. 

Is It Safe to Use an Online Car Buying Site? 

It can be safe to buy a car online but you do need to take some precautions. Don't give your personal information such as social security number or home address to a personal seller. Don’t wire money to an individual or give them your bank account information. Find a trustworthy and reputable dealer that is legitimate with positive reviews. Then fill out their online encrypted application and speak directly with someone from the company. 

Use your best judgment and do some research as there are online scams, stolen cars being sold, and cars misrepresented. 

What Are the Benefits of Using an Online Car Buying Site?

Some of the benefits of using an online car buying site include:

  • Saving time by shopping online or from an app
  • Saving money by staying at your home or office and not driving to dealerships
  • Comparing cars side by side easily and quickly
  • Saving cars on the sites to look at later 
  • Avoiding hours in a dealership haggling or waiting on customer service 

Can You Negotiate Price on an Online Car Buying Site?

If the car is listed on the site by an individual owner, there may be more room to negotiate, but they may not offer financing. Conversely, if the car is listed by a dealer, they will most likely offer financing but usually already have their lowest price online. 

It also depends on if the car is used or new and how strong your credit score is. It doesn’t hurt to ask and you may get a bit knocked off the price, a reduced delivery fee, or even a discounted warranty.
