what should I watch out for on 87-89s
My wife loves my targa and is even thinking about selling her 328iC for an 87-89 because of the G50. We'll be looking for a coupe this time because we don't need another fair weather vehicle. I knew to check into the chain tensioners, pop-off air valve, leaky lower valve cover and poor oil cooling w/trombones on my SC before purchasing. Besides gtg a PPI, what upgrades or updates should I check into? Also, is the G50 that much of an improvement over the 915? I've never driven one and don't really want to be a lookieloo if there's not a vast improvement.
