Don’t believe everything you read online.Wish the F355 wasn't a maintenance hog, or I'd be driving one right now.
I had mine for 12 years and apart from one significant issue (which had more to do with an inability to properly diagnose the problem than anything else) it was very reliable.
Like any old Italian supercar, if you buy a poorly maintained shit-box you can expect a nightmare.
Buy a good one and look after it properly and it’ll be fine.
I miss it, but the Emira is a worthy replacement.
