Topline Power Sports was the worst company that i ever had to deal with when buying a product. Long story short, i spent about 3k on a go kart and after many calls and emials from me to the only sales rep (Doug) they never sent me the gokart that i bought. This is called mail frauld. i can't tell you how many time i herd, should be here soon i call you at the end of the day after i check the shipping report and no call ever came and i had to cancel plans with my son time and time again. BUYER BEWARE!!! By the way they can't even keep there website up, i think you can take a pill for that. read full review »
