Sorry for not posting earlier. Here's my top 6 future cars I am impatiently waiting for (listed in order of importance).
1. BMW M3
This speedster, now outfitted with a long-awaited V8, will retail for about $53,000. Sticker shock?
Drive the M3 virtually here.
2. Lexus IS-F
With 400+ horsepower emanating from its V8, the IS-F is the fastest Lexus ever! (It's also my favorite Lexus, second to the LS 600hL) With an aggressive body kit and sleek pearlescent blue-purple paint, this ferocious IS could be coming to my father as a courtesy rental car next time he brings his RX 300 for service...

3. Nissan GT-R
The new iteration of the famous Skyline, this car has been captured by many spy car photographers alongside a 2006 Porsche 911 Turbo, considered to be a benchmark car. This automobile already has been booked to appear in Need For Speed: ProStreet and Gran Turismo 5 Prologue.
4. Subaru Impreza WRX STI
This hotly expected version of the 2008 Impreza will only be available in the ugly hatchback style

5. Audi TT Coupe
The best-looking TT so far, this mini-rocket is quite luxurious, like any other Audi. Beneath the more-aggressive exterior lies a 250-hp V6.
EDIT:
After a comment about this post, I have decided to add another car to this uber-quintet of sports cars: the Hyundai Genesis Coupe.
6. Hyundai Genesis Coupe
The concept version of the next-gen Tiburon, this 300 hp speedster will provide thrills worthy of an Evo/STI with a price good enough to make generous parents buy their college-bound kid a Genesis Coupe, rather than the traditional used clunker.
