I spoke to the previous owners of my 94 last night. Well let me say this; the 94 has 253k on the body, but while speaking with him I told him I've had to add a quart of oil about once a month. He goes "Hmm. How many miles does the odometer say?" I told him 253 and he says, "Well the motor does have 453 THOUSAND on it." I say "Huh?" (I knew the motor was replaced). He goes "Yep, I replaced the motor in that car. When I put the motor in it it had 439k on it, which is what the car had at the time." So I think this is the longest running 3800 I've ever owned. I do have proof to any nay-sayers but I'd have to get it from him. I thought it was interesting 453k on a Series one and running like a champ I'm so proud. lol

WOW.. i was just telling someone that 3800 last forever and can have over 400,000 miles on em with routine maintenance and car... Here is proof

so wait..he replaced the motor in the car with a motor with 400k+ miles? Why?

On a side note that is awesome it has that many miles. These motors are truly great!

yeah that dosent really make sense, but it'* awsome that gm can make such an intense engine.

I know that what I said I went wait your telling me when the motor went in this one you put a 400k plus motor in. So I ask why he goes cause they're amazing motors and last forever and I go well i knew that and he says here is you proof lol

WOW... Proof that they're just as reliable as any Toyota.

Wait, he replaced an engine with 400k with another one with 400k miles, but claims that they last forever?

Come on over, and I'll show you how long a 3800 won't last. LOL

Ever owned a Series 1? I can tell you exactly how long they last. At 217k miles, I blew a lifter because I overheated the engine 5000 miles before that. I checked compression and I was within 2 PSI of 188 PSI on all 6. I am 100% sure that had I not overheated it, it would have been perfectly fine.

My uncle owned a 1992 Bonneville with a Series 1, and drove that to 285k miles before he sold it, in perfect running condition.

My 1993 Custom had a Series I with over 275K before i gave it to my, which he drove for many many months till it was impounded, and still ran perfect. Ive also had Non Series 3800'* with as many miles

yep this is a series 1 with 453 k and running strong
