exchange motor, or what other options?

[farangatang 3]

my apologies if this is the wrong section to post this

unfortunately my little 1998 Nissan NV pick up now has a blown head gasket,
possibly caused by not being started for over 2 years due to Covid19 travel restrictions & humidity corrosion etc.
It still has registration until October this year.
a local Pattaya mechanic wants over B35k to repair it,
I doubt my car is even worth that much!
I'm open to all suggestions what to do with it ?!?
are there any car wreckers in or near Pattaya?
or anywhere to get engine exchange?

appreciate all suggestions
