All that is old-school thinking, and it was correct in the early days of R3E but it was never really that complicated to me. The link Fanapryde posted is the one you need. The only real math involved is converting euros to your local currency, but Google takes care of that. You can buy 10,000 VRP for 65 euros which is a smidgen over $70, so not really much more than a typical AAA title which are usually around $60-65? For some reason the store isn't showing how many VRPs are required for the Premium Pack but when I did it I still had enough left over to buy the next couple pieces of content that were released. After that, yes you have to pay for any new content, but that's not unlike DLC for any other game so I'm not sure why that would be an issue. And typically their content is pretty cheap, $2-3 for a car and maybe $5-6 for a track.
The reasoning for the VRP system is that they have contests that give away real prizes and if they did that with real money it would run afoul of several countries gambling policies. So they have to use a fake currency substitute to stay out of trouble with the federales. Not ideal for the customers but it's really not that complicated and not nearly as complicated as it used to be. It's a unique game, and has a few oddities, but when everything is right it feels very good and is really fun. Also, the R3E players are the friendliest and cleanest driving racers in the genre IMO, and the devs are awesome.
Buy your bulk VRPs here. If you want the best bang for your buck always buy bulk VRPs instead of buying directly from the store or from Steam (never ever buy any R3E content directly through Steam, you will pay more than necessary).

Don't get me wrong, I love trying out all kinds of sims and RRRE is definitely up there, but if you have to do hours of maths just to get the best deal and unlock all content then I'll pass.
