Moderate sample. 357 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1999 SYM Red Devil is a serious reliability gamble—just 25.7% pass first time against the UK average of 80%, making it one of the weakest performers for its age. The good news is that dangerous defects are rare at 2.2%, so safety isn't the main issue; instead, you're looking at chronic wear and frequent smaller failures that rack up repair costs.

These machines are running low mileage for their age (median 13,617 miles), yet still struggling to pass, which suggests poor storage or maintenance rather than hard use. With an average of 0.32 failures and 0.5 advisories per vehicle, expect regular trips back to the garage if you buy one—get a full pre-purchase inspection from a specialist and factor in ongoing maintenance before committing.

The 1999 Sym Red Devil passes its MOT first time at roughly the UK average rate (79.1%) — solid but worth checking this vehicle's history carefully.
