How to get trim level from plates?

[I drive a VL Commodore]

Got a bit of a problem here. I have what I assume is a fairly basic VL 3.0 but I can't work out what the trim level should be. All the badges are gone bar the Electronic Injection on the sides, it has [RTS]Commodore SL on the dashboard but I know that isn't the original one so I can't say if it is in fact an SL or not.

The builders' plate reads as follows:

MODEL: VL8VK19-A80
BODY: 286495-A
TRIM: 151
PAINT: 20 013-D
BUILD: MAY 88

Could someone decipher that for me else link me to the appropriate material? Cheers.
