I drive a mixture of Suzuki offroaders .... vitara heavily modified....... sj416 heavily modified.......... sj410 modified. The 416 started life as a sj413, then had a 1600cc engine installed, paddle clutch and bigger wheels fitted..... the sj410 has a spring lift, body lift and 31x10.5r15 wheels plus a bedford rascal carb. carrying one or two people I wouldn't say the 410 is lacking much grunt compared to the sj416. Have 3 or more in or go extreme off-roading then you notice the difference. The sj410 is great for green laneing and on the road its ok to. The advise I would give is go for either, unless you are offered a Sammy which has a wider wheel span.
The sj410 could be for sale if you are interested.
