Could be-last time I drove it for 3 days I was thinking to myself"What a nice running SDL" ran and shifted great, felt like a Tank on I-95--the owner/head mechanic truly does not have the time to check it out-he's swamped with work-my VW TDI has been in his shop for a week with a hard starting issue. I don't mind a bit, he always gives me one of these as a loaner--keep it for a month or two!
