Racer's Island has a store with both of the Alacer line of cars on sale, I didn't get the vendor for the sport & changed at Silver motorsports BUT you can grab a TRez supercar there for 99L! Just search for racers island and TP in, you will be in the mall and then you can go check out the mall.
When you find my section(over at the far side of the mall near the TP in point), 'Alacer Cars' you can get yourself a TRez for 99L or a sport 7 for 99L. If you have problems with sculpts you may really like the sport 7, it will make less drag on your Frames per second count than most high prim cars or sculpties! It has mouselook and then you can really save some lag! Track list included in the box on purchase, a few tracks you may never have found I bet!
I update these cars, so every year or two you get an update with new tricks and features! Next update will have special Display cars for when script caps come out!! Shadows and a set of special vehicle poses to chuck on it so you can hang out and take some pics at your pad or favourite hang out!!
Maybe join the freebies of the month each month! I am behind after calamities and laziness collided this summer, but I have like 2 months worth after this update! Free vehicles, in there right now is a hover craft(sci fi style!) with mouselook and super low lag with a h4 update to the pogo stick and a added active camera to the p0go stick for a funner angle and better mechinima!
