A Coupes' only had it really, if it's not been looked after or badly crashed.
As you're aware, they are older cars now, so expect things to wear out on them.
Bodywork side of things, most are generally still in good condition. It's not often you see a rotten one. Even if you did, it would just be in usual places you'd expect from a car that age.
The engines are quite good, especially if looked after and serviced at regular intervals - even an oil and filter change will do if you're skint.
Italian cars are a bit more critical regarding oil levels, than a lot of other cars. They like oil and shouldn't be run low on oil, unlike, say, a Fiesta, that would survive being run low on oil for months, without damage.
A car with more than 100K will have likely to have had the bigger jobs done already, such as turbo, clutch, etc.
Lack of oil and cambelt breaking is the biggest failure, so at least make sure the cambelt and auxillary belts have been done on your future Coupe, or budget around £500 to get them done asap, if there's no record.
A standard car, with some history would be a good car to go for, especially if over 100k.
Most of us on here are over 100k mileage wise
