I've heard horror stories about Carmax, that they undervalue trade ins, and push warranties hard, and their cars are overpriced...
What would you expect from a retailer started by the same people that brought us Circuit City (ex employee of Portsmouth NH Store 4116 here, I still have nightmares, especially regarding the words "performance" and "guarantee", an absolutely horrid place to work or shop, we were expected to pressure customers into purchases, and then hit them hard with the "PG", in the Circuit City dialect of English, 'No' didn't mean "No" it meant "I need more information" we were expected to push the PG at least 3 times during the sales pitch/demo...
So, that's what I was expecting when I went there, a hard sell, high pressure sell, and a hard push on the extended warranty.
What I experienced was the exact opposite, low to no pressure, my salesperson was pleasant and enjoyable to talk to, we actually spent more time chatting about how she was new to the area (came from California) and wasn't looking forward to her first New England winter, scared about driving in snow, I gave her a few hints (snow tires are your friends, find an empty parking lot and practice emergency maneuvers, plan on doing everything more slowly, make sure to bundle up and have spare clothes and even a sleeping bag in the car just in case (set up a bug out bag)...
Eventually we got back to the car, she offered a 24 hour test drive, which I took, and was pleased with the car so I came back the next morning (after having the car evaluated by my mechanic first) to purchase it, I dealt with another salesperson (they apparently are not on commission, unlike Circuit City...) to complete the sale and she only lightly presented the extended warranty once (these are your options, this is the price and what's covered, and it can be returned after purchase if you don't use it) and it was a take it or leave it presentation, no pressure, I was given two prices, one with the warranty, one without.
I made my decision, and during final prep, they found the rear seats had a major ink stain, and put a new set of rear seats on order, as well as a few other maintenance items needed, they treated my 12 year old used Toyota purchase like it was a brand new car!
This was the most pleasant car buying experience I've ever had, and I've been driving since 1987 (and *BOY* am I tired! ;) )
Highly recommended
