the clutch is very heavy on the 964 and 993. so with age and knee problems it might not be a good choice for everyone. that is why i sold my beloved 993 TT some years ago, although it already had a hydraulic supported clutch. Luckily, Sergio Marchionne (RIP) had the idea to build a go-cart-car like the 964 RS/ 993 TT but with automatic shift
