Hello! An acquaintance of mine would like to buy a used 996, year of construction approx. 99/00 with 221 kw (300 ps) and have a few questions about it: 1. Is there a clear difference between “sports seats” and normal? 2. Is the front-mounted conversion to the facelift with the parts of the Turbo/4S possible, i.e. bumper, fender and headlight? 3. Is there a great difference to the 235kw engine from the facelift? 4. Is a C4 with all-wheel? 5. What does the “PSM” bring? Should you definitely place importance on it? 6. – A question that is not important, but important!! – Can the glove compartment be retrofitted by the Facelift or do you need a new dashboard? 7. Oh yes, one more: Does the original Porsche Klatnauspuff also fit the 3.4 liter engine or is there a no flap-nauspuff? So that’s it… To a few answers n I would be very pleased. Greetings cabriofreak
