Where now comes a totally different car I've ever owned , a car with supreme traction all wheel drive and a turbocharged engine that will make sure you stay in your seats .
The Subaru WRX STi , first of it's kind in my collection because it's the 1st 4 door car I've ever owned.
Now a little run down on the technical aspects of it for the techie's out there

Then comes the layman term of driving impression. 350z VS STi
350z
- Low and mid-range torque is marvelous with the 3.5 liter engine
- although it is a rwd , the TCS and VDC control are mediocre comparing it with other available system out there but it did save my friend's ride in the snow back in Wichita
- straight line acceleration is good for city driving but not on the drag lane
- Going to 200km/h without downshifting is easily attainable while cruising , all you have to do is stomp your foot pedal to the metal
- Only makes you smile above 3500rpm
- Low end and mid range is just ok since it's a 2.5 liter engine only
- Once the boost comes in , it can be tricky to get a good line especially on slaloms.
- high potential for more horsepower
- Best added bonus is the ability to fetch your friends ( boatload of them =) )
- The amount of aerodynamics on this car is amazing , u get all this winglets etc even on the front bumper and side mirrors.
The interior seats with the STi embroidery , really suck compared to the Evo Recaro seats.
The gauge clutsters are amazing since they operate on stepper motors , it gives you a cool welcome greeting like the DEFI BF series gauges.
The interior is not that great compared to the Z , and so is the radio ( but who needs them anyway when you're at the track ) . * Please ignore the plastic on the pedals as I've forgotten to pull them out when i took her out from the show room*
Here you can see the Stingray classic corvette sitting behind it. The best corvette ever made in my mind
