Camping, Daily commute driving 50km o/w; budget $25-30k

(Melbourne Aus). We want to upgrade our x trail with a PHEV or EV. For the size of car we want (similar to box shape of xtrail) i don't think a second hand EV is in our budget. Mitsubishi PHEV MY20-MY22 is, but wondering if theres other options. BYD atto 3 doesnt have flat seats when they're put down... Use case: driving 50km (90min) each way to work (mostly M1 and 60km roads); need to throw a bike in the back; want seats that go flat (not with an angle) so we can sleep in it when needed. Budget $25-30k Any other cars we could look at, and can someone pls explain how we would best use a PHEV? Also anything to ask/look out for with a PHEV when shopping? (Am a little clueless with cars) Many thanks!
