Nah...
forget the BX's and Saabs... You only live once ... Go and get yourself a CX GTi Turbo ... Mechanically they'll outlive us, however you'll be sure to know it's wiring looms quite well within a short period of time.
these cars are what Citroen is all about, decent seats (unlike the Xantia and BX), proper wishbone suspension, comfy ride, great handling (once you learn how to drive them), fantastic brakes, effortlessly fast ... It'll leave you Xantia CT turbo's for dead, while using much the same amount of petrol.
Go for it !!!! No doubt you'll be hooked in no time and have a yard full of CX "parts cars" and "restoration cases"
