Tom, this is totally the wrong place to be asking this question. The car disease is just one of those things - 'If I have to explain, you wouldn't understand'.
Go read Dave Ramsey's book like everyone else said to - pay attention to the part in there that says, "Saving money without a goal in mind is pretty pointless", or something to that effect.
It might not be the best 'first' purchase out of school, but don't ever let anyone ever tell you that you shouldn't get something you really want. Cars like that can be impractical, yep, but so are a lot of things that people do. I'd never let someone who's married with kids tell me about impracticality.
Besides...I really can't understand how THAT particular engine - the Gallardo's 5 liter V10 could POSSIBLY be that maintenance intensive. It's motor is basically 2 Jetta 2.5L motors - the cylinder head is essentially the same, the bore and stroke are the same, they're both naturally aspirated...what's left? Why can't it also go for a gazillion miles of day in and day out driving like a Jetta?
When I was curious about buying a car like that for daily driving, I basically went to a Ferrari forum and asked who did their own maintenance and who drove their cars a lot. Turns out the V8 Ferrari's are pretty reliable, and you can service them yourself, more or less. That really turned me on to the 348/355/360s. And there are a TON of those down here. Also, I'm really into the Ford GT, since that's basically a truck motor with a blower - something Ford knows well.
