Decidedly Unpleasant:
You know what sucks? Leaked transmission fluid on a previously unspoilt garage floor. You know what really sucks? Taking your new car back to the dealership for repairs just 4 days after having driven it off the lot, especially when it’s your first car too.
Update: fortunately it was only a pair of loose clamps on the transmission cooler line, so I had my car back after 3 hours. Everything else has been just dandy.
