I still visit :-)

And my 2004 Gallardo is up to about 20,000 miles..still like new , no maintenance issues...it appears to be as bullet proof as my Hondo S 2000.

I have raced it ( smoked an F430) and driven it from Lake Worth to the Smokey Mountains in North Carolina 2 weeks of "mountain driving" :-) , and basically, the G is driven 3 or 4 days each week.
I do NOT see it as expensive to maintain, but you do need a really good mechanic like Murray of Bachus Auto, to make sure you stay ahead of any problems that could develop.
And, you need to drive a Gallardo fast, or you should not have one :-)
