Thank you; imagwai, Gambba and Albert-AMG.
David,
Besides basic oil and fluid changes, I replaced the exhaust with a stainless steel system, a larger 16mm rear sway bar, slightly stiffer springs all-around and Koni shocks. I removed the cylinder head (common issue) and replaced the gasket (head work included; seals, new guides and slight resurfacing) and reinstalled Viton O-rings and roll pins (were not originally installed), some years ago. Recently replaced the heater control valve (leaking) and fixed a blowing fuse issue, that turned out to be the emergency 4-way flasher. A dose of DeoxIT and exercising the seldom-used switch, solved the problem.
As you know, with older Italian cars, it's always some little thing to tinker with. Fortunately, I enjoy electrical troubleshooting, doing my own maintenance and really love that look of the 105 GT and 115 GTV.
Yes, the value of your model GTV have really increased, in recent times.
I'm sure you have seen the video of Chris Harris driving the Alfaholics GTA-R. If not, here it is...
