Hi everyone

want to get into a classic Turbo-Ford resto project, but was wondering if I should aim for an S2 Escort Turbo or a Fiesta Turbo. I like both cars a lot, but is there something that would make one of them more desirable/practical than the other? Like parts availabilty, easiness of working with the car, better handling once improved, and such. I would like to keep the engine and looks fairly standard (Mint factory look style), just improve the usual weak points these cars had like brakes and suspension, add LSD (In the Fiesta) extra gauges and such.

Thanks for any advice!
