Welcome to TM you come well prepared in experience, I ran a Reliant Scimitar GTE for several years and learnt a lot about missing earth return wiring.
The Plus 8 is a great car to live with providing your expectations are not a nice silent quick dry tourer.
The suspension can be played with extensively mine just has adjustable Koni's on each corner and that suits me fine.
The best advice as always is to drive at least 2 examples to arrive at a kind of handling benchmark, a well maintained one should feel taught and precise in steering.
I have owned 3 cars 2 Plus 8's and a Sport they have never let me down in 50,000 miles and ironically the brand new Sport bits kept falling off it all the time but they were only cosmetic and just glued on..
Good Luck and enjoy choosing you have a good selection right now.
