I just got APR chipped today (finally!). Right after I took it back from the guy (who test drove it), I smelled something like either a just-lit match or a just-put-out candle. It took quite a while for the smell to go away entirely (at least I think it's gone away now). I'm pretty sure the guy red-lined the car, which I never do. Is this just a normal consequence of driving really hard, or is there anything I should be concerned about?
