I have a fondness for Mk4's. My first new car was a 99 GTI.
The V5 always was an unusual one. Parking sensors were a rare option. They came with a different shaped rear valance to accommodate them, as the standard one was more rounded. Although leather was an option, I don't think that the Recaros were. They are likely to have come from an early GTI or V6 4Mo. Having said that, yours being a late model may have had more options available as VW used up all the spare stock before the Mk5.
