man, this sucks. i hope you find the guy who did this because i highly doubt it was caused by the battery. it just doesn't make any sense why would the battery just all of the sudden burst into flames? 10,000 is a lot of money to put into a car, it must have ran like a dream other than the minor clutch problem you were having. it was a beauty of a car man. im not a big fan of vinyl or any type of graphics on a car but it looked pretty good on yours. if you find out who did this i hope he/she goes to jail for a long time and realizes arson isn't cool.
again man, sorry about the car it sucks.
talk to you later.
