Opel Monza GSE | Spotted

The GSE badge is back - time to revisit an old school hero

The GSE badge was a good one to be resurrected by Vauxhall and Opel, even if it should now be written GSe. It rolls off the tongue quite nicely, it sounds appropriately sporty without being OTT, and it’s always handy when an old name can be reused for the electric era. So expect many more like the Astra, Corsa, and Mokka, basically.

The return for the UK market of GSE is notable because there has only actually ever been one previous model sold here. There have been GTEs, GSIs, SRIs, HSRs and VXRs aplenty, but only one GSE: the Monza. Now there’s an evocative name, Opel Monza GSE. The ultimate version of what was basically a Senator coupe, it came with all the goodies expected of an early 80s coupe: digital dash, Recaro seats, strakes where strakes didn’t really need to be, and a burly 3.0-litre straight six under the bonnet. It may have been the only GSE ever sold here, but it remains fondly recalled by enthusiasts - how could something this handsome not be?

Plus there’s the fact that the models like the Monza (and the related Vauxhall Royale) were never replaced. Nothing burnishes a reputation quite like the end of a lineage. So seeing any GSE these days, more than 40 years after the last one was made, is notable. But especially so for this one, as it’s modified, magazine featured Monza that’s had a huge amount of everything invested to make it one of the best in the world.

Those with very good memories might recall that this Monza has featured before but, quite frankly, it’s cool enough to have the limelight once more. Especially at £5k less than it was advertised for in 2022 after just 1,800 more miles; it’s nice to see, for buyers at least, that classics can go down in value as well as up. The headlines for this one are a 24-valve engine conversion from a Carlton GSI (the standard 3.0 was 12-valve), which will bring a useful power gain; it also has working air-con and a sunroof, both handy going into summer; oh yes, and the small matter of £100,000 spent over the years on maintenance…

Actually, maintenance sells it short, because there are elements of restoration in that incredible spend as well. This Monza really is an extraordinary example inside and out, a testament to the money and effort that’s been spent on it. The six-figure claim was made last time this car was sold, so it probably hasn’t benefitted from much recent work (apart from the wheel swap); but then having covered just a couple of thousand miles since it understandably looks absolutely as good as it did. There looks to be a newer stereo now.

And when contemporary E24 BMWs are for sale at anything up to £130,000, paying a little more than £20k for a much rarer Monza doesn’t sound like a bad deal at all. It’s hard to imagine, even as a 42-year-old car, that there’d be very much to work on given the scope of the recent overhaul. All that’s hopefully on the to do list is to drive and enjoy, which shouldn’t be very hard at all.
