No clear winner. Once age and mileage are allowed for, they pass the MOT first time less than 1.5 points apart. The best bets are X1s registered from 2010 onwards, and X3s registered from 2005 onwards. No years of either stand out as ones to avoid.

How often cars from each registration year passed the MOT first time, against the average car of the same age and mileage. The figure is the difference in percentage points.
Each block is a registration year: the year the car was first used. Tap or hover over one for its figures. Blank means too few MOTs that year.
Points against the average car of the same age and mileage, with each year's most common failure. Less than 1.5 points apart counts as either.

The failures testers found most often on each, against the average car of the same age and mileage. Both charts use the same scale.
What testers most often noted as advisories on each: wear that passed but was close to failing. Figures in brackets are for the average car of the same age and mileage.
No clear winner
For cars registered 2014 to 2021, X1s passed the MOT first time 5.7 points above the average car of the same age and mileage and X3s 5.2 points above: less than 1.5 points apart. Choose by year, mileage and fuel instead.
+5.7points against the average car of the same age and mileage
+5.2points against the average car of the same age and mileage
There's no clear winner at the MOT. For cars registered 2014 to 2021, 84.9% of X1s passed first time, 5.7 points above the average car of the same age and mileage, and 84.4% of X3s, 5.2 points above.
None stand out: every registration year is within 1.5 points of the average car of the same age and mileage, or ahead of it.
None stand out: every registration year is within 1.5 points of the average car of the same age and mileage, or ahead of it.
Over 120,000 miles: X1s 5.8 points above the average car of the same age and mileage, X3s 8.1 points above. So the X3 holds up better.
X1: tyre damage (has a cut in excess of the requirements deep enough to reach the ply or cords), on 2.1% of MOTs against 1.5% for the average car of the same age and mileage. X3: coil springs (fractured or broken), on 2.2% of MOTs against 2.1% for the average car of the same age and mileage.
Data. Every car MOT in Great Britain in 2025, from DVSA's anonymised MOT test data: 112,196 X1 MOTs and 106,562 X3 MOTs. Retests are left out.
Against the average car. Each model is compared with the average car of the same age and mileage, not with each other directly, so a newer or lower-mileage model doesn't win for that alone.
Which is more reliable. The answer uses cars registered 2014 to 2021, the same years for both, as the rivals table on each model page does. Less than 1.5 points apart counts as level.
