I wonder how many Spyder owners are a little miffed that their car doesn't have a glass engine cover. Or how many more Spyder owners there might be if indeed Audi offered this (even as an option). Some folks I know who drive Gallardos still kick themselves each time we meet up and they see my R8 coupe with the engine under glass and they kick themselves because they opted against paying the $5,000 or so for that option on their baby Lambos.
Is it only a matter of time before some very clever people come up with an aftermarket solution for this? Or is there some complicated reason why this cannot (and has not) been done?
