They have some suspension quirks, but no more than a lot of other cars do. You can actually ignore the clonking for a long time before it becomes critical to fix.
No you can't.
Well, if *you* can, point me in the right direction and I'll set up a car lot specialising in Stilos.
It's a development of the Brava / Bravo and got a lot of bad press, a lot of it undeserved. I wouldn't have most of 'em, but a JTD or 2.4 Abarth would be fine, IMHO.
The biggest failing of the Stilo is that it *didn't* have the looks to compensate for shortfalls elsewhere. Something that has been resolved in it's replacement.
