Grandma’s 1978 Pontiac Grand Prix LS

1978 Pontiac Grand Prix LS

Disclosure: This site may receive compensation from some link clicks and purchases.

This Pontiac Grand Prix belonged the seller’s grandparents. They purchased it brand new and took very good care of it. The seller includes a detailed story about the car and how it was mostly used by his grandma. Unfortunately, he made a few mistakes with the paint after he took ownership of it, but it still looks like a respectable cruiser. The interior is clean and has some awesome hounds tooth patterned seats! It’s nothing fancy, but it’s getting harder to find grandma cars like this, so I thought it deserved a mention. Find it here on eBay where bidding is at $1,725 with the auction ending tomorrow!

    What a great color, a great interior, and an even better story!

    Well, I wondered where/when if ever a 78 Pontiac would show up as a car of interest! One of the very few cars I bought brand new when I was fresh out of college was a 1978 Grand Prix. Mine was silver outside with a red “velour” interior, bucket seats, glass t-tops and the wire spoke hubcaps. It was a very pretty car for being a 78 Pontiac. But it was a 78 Pontiac!! We had just had our first child, so I sold my 63 Jag XKE Coupe that was my daily driver to “do the practical thing!” I eventually painted the Pontiac black, then sold it a few years later. Then I kinda went back to older cars and I don’t think I have bought a new car since then! Probably would be kinda nice if that XKE was still in my garage!

    Nicely optioned car. Plus it’s got a V8! It’s an LJ, they didn’t make and LS model in 1978. The models were base, LJ and SJ. If I remember correctly the color was called Seafoam Green. I was a porter at a Pontiac store when this was a new car.

    Don’t hate on me but if I had to drive one of THE most hideous body styles GM ever produced, with interior designs to match…it’d be this GP and not a Cutlass, Monte Carlo or Regal (or whatever Buick’s was).

    Sad when I think of what the GPs and Monte Carlos were like before the downsizing.

    Don’t hate the color, style or interior. I am a body man/painter & could easily make this a daily driver/ grocery getter for a fraction of what you can buy a cheap piece of new foreign crap. Just my opinion, not looking for a job—way out of my area.

    Some people may like this version but I was disappointed when Pontiac changed the design of the Grand Prix. 1977 was the best design ever and they took a monstrous saw to it and chopped it off square. I might add that the LeMans got changed too. I bought a ’78 Grand Am which didn’t seem to have suffered as much as the others but still fell way short of what used to be.

    We had an Avis franchise in our Texaco back in `78.
    Avis pulled out mid year, leaving a Grand Prix in the parking garage across the street in the Holiday Inn. That car sat there for more than a year. despite repeated calls to Avis corporate. I think it had about 1,100 miles on it when they finally showed up to retrieve it around 1980.

    My landlord sold me one of these that didn’t run because the plug wires were toast for $200 in the mid 80’s. It had a 305. I quite enjoyed my first personal luxury car. For the money it was very comfy on the highway and served me well till I unloaded it. Always was ugly, then and now. Only V-8 I have ever owned.

    I had a ’78 Grand LeMans, so similar to this car in many ways.
    The V8 in Pontiacs were 301’s. My only complaint for that car was the tires which came on it. Uniroyal, I think. Darn near square. I’d had enough at 20K miles, and invested in a set of Michelin. What a difference!
    One of my friends still mentions that car on occasion, as the one he really liked. The interior was plush and comfortable, and since I had bought it new, it was always kept clean and properly maintained. Hated to see it go.

    When I got my learner’s permit, the very first car I drove was a 1980 Grand Prix.
    After seeing this one, however, I’m disappointed that my dad didn’t spend a little more time car shopping. Ours didn’t have too many — if any — options. Just a 3.8 V6 with an automatic and a radio. That was about it. This one is LOADED compared to the one that we had! This one looks to be a good, honest car. Interesting find!

    Neighbors had a burgundy one like this. Would look really nice repainted with a set of WS6 snowflakes.

    Sold for $2225.
    Bargain city. There is a lot of life left in that car. Someone will be enjoying a cushy ride for years.

    IMO, this is THE UGLIEST car GM ever made. Sorry. Too Boxy and that tall space between the wheel opening and fender tops was hideous. It may be a great car, but not for me.
