if i were to buy a hitch for a 95 ssei, how much could I tow? i have a snowmobile and currently use my dad'* van to pull it when I go anywhere. i'm guessing that the trailer weighs around 2000 lbs with 2 snowmobiles on it. would the car be good enough to pull it?

I would not tow anything with my Bonnie, except a rice burners butt down the strip.
Is there anything else you can rent when you need it?

i would just check craigslist and buy a beater truck. save of of headache in the long run

Don't do it. I believe the Bonneville is rated to tow 1000 pounds with a 200 pound tongue weight but that is with no extra vehicle weight (passengers or stuff in trunk). You don't want to overload the brakes and certainly not abuse the transmission with the extra weight. Check the GVWR that is listed on your door. One sled may be OK if the trailer is light.
