Larchmont Chrysler Jeep Dodge Ram

I had a service light on and got it checked at Larchmont-Chrysler. They said it was engine and billed me $2,000 for the work. One month later, the light came back on so I visited them again for diagnosis. They said this time it was the transmission and it would cost $3,500 (before tax)! The car is not worth all those money 'cause it's old (03 Stratus), so basically they're saying to buy new one. When I asked the trade in price, they said $1,500. I felt like humiliated that day, and I blamed myself to visit them in the first place. They've been trying to call me for new car sale but I'm trying whatever I can to avoid them. Looking back, the engine repair seems to be overpriced as well. I should've visited non-dealer- auto shop with the old car like mine. They tried to do the same to me with the transmission. I'm just glad I can tell other people out there about this malicious dealer. Yes, you've been warned.
