B7 RS4s are indeed sought after, but here’s the rub. There are some beautiful examples out there, but there’s also some high milers, and that’s reflected in the price. They also need to be driven, but I appreciate it would be a summer car, rather than daily driver. €50k is roughly £42k GBP. That’s top money, and I’m not convinced this car, although desirable necessarily falls into that camp. Again, just my opinion. Few reasons, I think the Avant is generally more sought after, especially when it comes to resale. In addition, colour is everything. Sprint blue is attractive as a factory colour, but Audi also made the RS4 in Imola Yellow, which is very rare under their Audi exclusive scheme which would have been a custom colour. It’s not everyone’s cup of tea, but it has provenance having been used on the B5 RS4 Avant a few years earlier. History is everything too. To command a top selling price it needs documented history from new, all keys, and any remedial work such as a recommission if it’s been in storage, so basically it’s turn key and go. My advice for what it’s worth is to potentially travel and set up a few appointments. At the end of the day these are getting to be old cars, so pictures can be deceptive. What are undersides like, any corrosion? Also, do some research on parts availability.
