Help an old car around nz to show off her chrome

Hello I’m Thomas Findlay 34 years old .
In New Zealand.
I was happy for 12 years working hard on a sheep and grain farm mainly stacking 40kg bags of seed grain and sometimes helping out with catching a few 120kg sheep and then the farmer (owner) built another big shed for the roller mill for making supplementary feed loads with rolled grain like wheat and barley and the odd time oats mixed in to load on to auger trucks and deliver to cow farms with milking sheds and I was happy to end up working longer hours at nights at the busy times.
Until 2018 happened , my dad was sick for awhile from having diabetes for about 56 years he was born in 1949 so he did very well living life to the fullest but September 2018 sadly he passed from kidney failure and he found the Rx2 bought it and our family still has her , I’m the only one in our small family doing my best to keep her going and maintained and the only one who wants to drive her around to car shows or just around to show off a beautiful about to explode rotary engine car she’s pretty much my 45 year old sister.
Also sadly now I’m to sick and weak to work , I did a months or three weeks of work at the same farm I used to work and my muscles are now to weak to lift any thing heavy or even push strong heavy sheep up a drenching drafting race , can barely lift any 40 kg bag of grain I used to have absolutely no problem lifting straight up from the floor to my shoulder for some one who wanted a bag of grain or a couple for seed or feeding animals (the bags are marked treated for seed or untreated and feed oats or feed wheat so no animals were ever fed the treated grain).
3 years I’ve been to many doctors appointments , I’ve even had to be sent to hospital by ambulance for strong abdominal pain and the country farming town where I live health system to this to this day have not found anything wrong with me and sent me home after basic scans and tests and I’m still in constant abdominal pain everyday but because of my dad I’m sort of the same as him , optimistic and just want to live life the best I can , be generous and help people out when I can if I’m able to or push a little bit through the abdominal pain I’m in.
I’m not a person to ask for help , actually this is the first time in my life I’ve asked for this kind of help , I want to keep my dads car going and look after her the best I can , also being she’s a 20 year old 12a Rx7 rotary engine dad bought that rebuilt when the original Rx2 12a rotary engine cracked a housing end or center on dad coming home in about year 2000 around that time.

Ok wow sorry for this long as hell sad story but hopefully it was worth reading and thank you for reading.

Faithfully hoping
Thomas Ian Findlay and Findlay family
