I would suggest test driving a few different models before you commit. Its often said "dont meet your heros" and I have found the same with cars, driving your dream car can shatter the dream. Whilst driving a Testerossa was "fun" I was so pleased to be driving my 430 home. Not sure what sort of money you are thinking of spending but you will probably have lots of different and/or "newer" models in scope. Also it might be easier to sell on a 308/328 rather than a Testerossa when you want to change etc.
On the Testerossa fuse boxes can be an issue, as they are a poor design and badly made. This can give all manner of problems - a potential electrical fire ANYWHERE in the car - and difficult to find electrical faults as you go chasing a particular circuit on the wiring diagrams then discover the fault has been caused by random fuse box shorting out on a different circuit (with a higher current rating so the fuse keeps blowing or the loom catches fire !!. As an example a friends TR had an electrical problem with the window switches that set fire to the loom :shocked
. You cant see all the circuit board in the standard fuse box so making it even more difficult to track faults. There are several companies that do upgraded fuse boxes......... there is a reason for this !!
There were also some problems with clutch slave cylinders (About 3 years ago ??) as no seals were available from the factory and some company made some replacements which also leaked. I would want to do some research on this before committing to buy as its something that will need doing at some time soon. (The seal was used on some other models, and at one stage Lovetts had a few cars in bits waiting for someone the produce a seal that worked)
I have also seen oil leaks from the rocker box covers, along with very poor repairs involving industrial quantities of silicone goo. MY friends TR leaked oil like the Exon Valdez :thumbsdow
Finally how big is your garage ??? TR these are huge :laugh: Brave choice for a first Ferrari !!
