Had the email to book my assesments today goto wait for my work to confirm what days I can have off now and book myself in

Five mins after getting this long awaited email I got a phone call for another job interview next month,now the dilemma is if I get this other job,will earn 35k basic,bit of OT and bonus will be about 40k plus ill get a fully expensed vehicle,no shift work either,its a job i enjoy doing aswell.
So the rail job may be an extra £75 or so in my pocket every week,but ill have to fund another family car,work shifts and not be sure if ill like the job either.
Will do assesments either way as would like to see if I pass them or not...but may be a tough decision ahead if offered both,as the old saying goes money is not everything,being happy in a job counts for a lot aswell.
