OK, it's at the end of FM4 rather than the start of FM5, but after the V8's I felt like doing a bit of tinkering. The result was a Gary-build Aston Martin DB5. Bear in mind it's only in B-Class when you see the stats.
Why is this a Gary car?
Stonking huge turbo
Well over 600bhp
Skinny stock tyres
Top speed in excess of 200mph
Why is this not like a Gary car?
Goes around corners (much to my surprise)
Surprisingly quick (the time in Test Drive around Old Le Mans would have put me top of my friends list with a 4:08)
Doesn't try to kill you
Brakes almost work
Any other details I need to know?
The tune is free
It's on my storefront, or
You can find it by searching for "Gary"
The car started life as an Aston Martin DB5 before the conversion to a DBG, so you'll need to apply the tune to a DB5.
