So, back in January a passenger knocked my shifter into manual with his knee without my noticing. I then went up a steep grade for more than .75 miles at over 70 mph in 3rd gear, resulting in limp-mode kicking in before I reached the summit of the pass. I had to drive it another 60 miles in limp mode before parking it (for the last 9+ month's). A local German Car mechanic gave me a $3,200 estimate - but the only two Smart car centers near me are in San Francisco and Sacramento - NEITHER of which are willing to give me an estimate over the phone. I suspect the problem is a burnt valve, possibly requiring head replacement. Has anyone experienced an issue like this before? And if so, what was the final bill? It's a 2008 Passion and as much as I love it, I'm not sure if I'm prepared to pay more for a repair than I did for the car. Any insight would be helpful . . .
