I'm very disappointed with the service from Len Stoler Chevrolet. I purchased a car last Wednesday. I had been inquiring for weeks and weeks prior, went to look at it in person and was informed the car was still in the process of inspection and that it would be ready June 24th. I went to Len Stoler to sign paperwork and place deposit and still the car had not been touched due to a part/oil pump they were waiting for in the mail that arrived on the 24th. A representative felt bad and told me the honest truth that they hadn't even started working on the car because they fixed two other trucks and put my car aside. Len Stoler put me in a loaner vehicle and informed me my car would be ready July 1st, possibly June 29th if they could. I called June 29th the car was still not ready and I was informed the car would be ready on July 1st, 1st, possibly June 29th if they could. I called June 29th the car was still not ready and I was informed the car would be ready on July 1st. After countless attempts of contacting on July 1st I was informed the car is not ready due to a part that didn't come in the mail until June 27th, which was hard to believe when the part had "already arrived on the 24th" the day I purchased the vehicle. I drove an hour away back to Len Stoler and looked at the car to see what work had been done up to this point. It hasn't even been touched. I am now being informed that my car will not be ready until July 8th. If the part did arrive Saturday. Len Stoler had Monday, Tuesday and all day of Wednesday to change an oil pump that only takes 4 hours max to repair. The repairs list were all minor parts, brake pads, alignment, etc. I have gone out of my way several of times to accommodate Len Stolers busy schedule and when asking what could be done for the extra wait I was told I was given a loaner vehicle that they could be potentially selling that I am racking miles up on which I am grateful for but wouldn't even be using a loaner car if the car was ready four weeks ago. I was also told I could take my deposit back but there was nothing else they could do since there are seperate managers for each department. All I'm asking is for my car that I purchased that was promised to me weeks ago. Is this normal for your company?
