superb residuals

Anyone know what the residuals are like on the superb? I've scoured the internet and seem to get a varied range from 43% to 22% (a fleet site it mentioned 22% CAP monitor RV on a SE 140), which sounded ridiculously low. Unless I've misunderstood how the values work.

I know a car is most definatly not an investment, but I don't want to end up with nothing after 3 years.

Size and residuals are about all that is making me think twice. Having had an hour test drive in a 140SE it was a nice place be, lot less road noise than my Octavia VRS.
