While on the subject the rear engined VW beetle was famous for catching fire used to have a short out in the battery and apprently once (urban myth) it got to a certian point and the heads that where made of magnesium would go up and you had to wait untill it stopped lol.

And nota John Bowe (ex touring car champion and bathurst winner for those not up to speed on ATCC) in an interview from street machine said he one had a moment of passion with a young lady interupted by his beetle catching fire.

Your not being entierly far most old rear engined cars caught fire one way or another (and suprisngly some still do) wether its from heat or another problem
