Re-sale? What's that. If it's Opel badged forget even considering that as an option.
No doubt if you are looking at buying one it will be stupidly cheap to begin with.
If it suits your needs/wants and your budget then buy it.
Don't buy it looking to sell it off again for similar money.
Due to Opel's pathetic 11 month stint here the prices with forever remain ruined on Opel badged vehicles.
Sorry to sound so negative about it all, just the way it is.
