If its anything like the I-Mark they had, you'd better check the oil at every fill up. They burn it bad....
I had a 91 Impulse and it was fun for what it is....handling was good on stock 185/60/14's
Anyhows, mine would burn up oil on the higher rpm long trips (anything over 80mph for a tank of fuel)....I drove 1100 miles....14 hrs.....and was close to 3 qts low....and I had just changed the oil the day prior to the trip.
Enjoy it....finding parts today might be an issue....good luck
